A new genus and species of polyancistrine katydid, Spinapecta alieniphaga gen. n. et sp. n. is described from Minas Gerais State, Southeastern Brazil. It is closely related to Polyancistrus Serville, but differs from this and other members of Polayncistrini (Tettigoniidae: Pseudophyllinae) in the unique structure of the male abdomen, sternal armature, and the female sound producing organs. S. alieniphaga appears to be a pest of Eucalyptus plantations.

The eelpout Leucogrammolycus brychios gen. et sp. nov., is described from nine specimens, five males (92–198 mm SL) and four females (99–205 mm SL), collected from off Rio de Janeiro state, southeastern Brazil, at depths from 536 to 632 m. It is mainly characterized by the following combination of characters: vertebrae 23–26 + 62–66 = 85–92; first anal-fin pterygiophore associated with first or second caudal vertebrae; scales absent; lateral line with mediolateral and ventral branches; upper lip broadly adnate to snout tip; gill slit not reaching ventrally to opposite lower end of pectoral-fin base; pelvic-fin rays 2; head pores relatively few, small, rounded; and whitish mid-body stripe forming a chevron on top of snout.

A new genus and species of glandulocaudine, Lophiobrycon weitzmani, is described based on specimens collected in headwater tributary streams of the rio Grande, upper rio Paraná system, State of Minas Gerais, southeastern Brazil. The inclusion of the new species in the phylogeny of the subfamily Glandulocaudinae proposed by Weitzman & Menezes (1998), reveals a sister group relationship between the new genus and the monophyletic group composed of Glandulocauda and Mimagoniates that currently form the tribe Glandulocaudini. The new species can be readily distinguished from all other species of the tribe by the autapomorphic presence in adult male individuals (with more than 23.9 mm standard length) of an adipose-fin whose base extends for almost the entire distance between the posterior terminus of the base of the dorsal fin and the base of the upper lobe of the caudal fin and averages approximately 25% standard length, along with the presence of globular expansions formed by the lepidotrichia and hypertrophied soft tissue in the middle portions of the first and second pectoral-fin rays. The diagnosis of the tribe Glandulocaudini is modified to accommodate the new genus.

Otothyropsis marapoama, a new genus and species, is described based on specimens recently collected in a headwater stream of the middle stretch of the rio Tietê, a river from the upper rio Paraná basin in southeastern Brazil. The new taxon belongs to a clade also encompassing the genera Schizolecis, Otothyris and Pseudotothyris. Otothyropsis marapoama is hypothesized to be the sister-group of Pseudotothyris and Otothyris based mainly on the presence of several derived characters of the swimbladder capsule and associated bones. Several paedomorphic characters shared by Pseudotothyris and Otothyris and their significance for the phylogenetic position of the new genus are discussed.

A new species of dactylogyrid monogenean, Apedunculata discoidea gen. n., sp. n. is described and illustrated from the gills of the freshwater fish Prochilodus lineatus (Valenciennes, 1837) in pisciculture ponds from Pirassununga, São Paulo, Brazil. Diagnostic characters of the new genus and species are: 1) vagina dextrolateral slightly sclerotised, opening anteriorly at level of copulatory complex; 2) copulatory organ coiled with two counterclockwise rings; 3) Accessory piece distal and not articulated; 4) body disk-shaped, lacking a peduncle.

A new characiform is herein described from the Eocene-Oligocene sediments exposed in the Aiuruoca basin, in southern Minas Gerais State, Brazil. Recently, two other characid species were described for this same fossil level: †Paleotetra aiuruoca and †Paleotetra entrecorregos. The holotype of this new characiform is represented by an articulated specimen preserved as part and counterpart, in which the most anterior part of the head is missing, including the jaws. Despite the lack of the diagnostic characters from the snout, a unique combination of characters allows its differentiation from other Neotropical characiforms, raising a new genus and species: †Bryconetes enigmaticus. Among these characters are: the presence of a supraorbital, dentary with inflated pentacuspidate teeth arranged in a single row, infraorbital 3 expanded and ornamented with punctuations and grooves, a large anal fin with iii+22-23 rays, and the caudal fin with 11 ventral procurrent rays of which the anteriormost are fused in laminar bones. A phylogenetic analysis using morphological data was performed and recovered †Bryconetes enigmaticus as a stem group to characiforms lacking a supraorbital. Based on the results of this analysis, a discussion of the potential relationships of the new taxon with other characiforms is presented.
